[0027] Please refer to Figure 1-Figure 5 As shown, the present invention provides a drawing door 3 and a refrigeration device 10 having the drawing door 3. The refrigeration device 10 comprises a box body 1 having a refrigeration compartment, a slide rail connected to the inner wall of the refrigeration compartment, and a drawing door 3 connected to the slide rail, so that the drawing door 3 can be drawn and connected to the refrigeration compartment in a front-to-back direction.

[0028] The drawer door 3 includes a door body 31 for opening or closing the refrigeration compartment. The door body 31 includes a door panel 311 and a door lining 312 fixed to the rear side of the door panel 311. The door panel 311 and the door lining 312 are jointly arranged to form a foaming cavity for filling with a foaming material. After the foaming material is filled in the foaming cavity, it solidifies to form a heat-insulating layer.

[0029] The door lining 312 has a slide rail connection portion 3121 for connecting to the slide rail bracket 33, and the slide rail connection portion 3121 has a through slot 3122 extending through the front-to-back direction. The drawer door 3 also includes a reinforcing iron 32 fixed to the side of the door lining 312 facing the door panel 311, and the reinforcing iron 32 is used to connect to the slide rail bracket 33.

[0030] The reinforcing iron 32 includes a connecting plate 321 extending from the door lining 312 toward the door panel 311 through the through slot 3122, and the connecting plate 321 is used to connect the slide rail bracket 33. That is, the connecting plate 321 used to connect with the slide rail bracket 33 is exposed to the outside of the door lining 312, which is convenient for connecting the slide rail bracket 33, and can be accurately positioned during connection, thereby preventing the drawer door 3 installed on the refrigeration compartment from being skewed.

[0031] Furthermore, the edge of the through groove 3122 has a reinforcing wall 3123 extending away from the door panel 311, which can increase the depth of the through groove 3122, thereby enhancing the stability of the connecting plate 321 and the stability of the drawing door 3 connected to the refrigeration compartment.

[0032] Furthermore, the slide rail connection part 3121 has a groove facing the door panel 311, and the reinforcing wall 3123 is located in the groove. On the one hand, the appearance of the rear surface of the door lining 312 is enhanced; on the other hand, the strength of the slide rail connection part 3121 is enhanced, the stability of the connection of the slide rail bracket 33 is enhanced, and the stability of the drawer door 3 connected to the refrigeration compartment is enhanced.

[0033] Furthermore, the reinforcing iron 32 further includes a fixing plate 322 fixed to the side of the door lining 312 facing the door panel 311, and the connecting plate 321 is connected to the fixing plate 322. The fixing plate 322 has the functions of fixing and enhancing strength, and can enhance the stability of the connection of the slide rail bracket 33 and the stability of the drawer door 3 connected to the refrigerating compartment.

[0034] Specifically, the door lining 312 has at least one fixing column 3124 protruding toward the door panel 311 on one side thereof facing the door panel 311, and the fixing plate 322 has at least one through hole 3221 corresponding to the at least one fixing column 3124. Through the cooperation between the fixing column 3124 and the through hole 3221, the reinforcing iron 32 can be pre-positioned, and during subsequent foaming, the reinforcing iron 32 can be fixed to the door lining 312 through the foaming material.

[0035] In a specific embodiment, the door lining 312 has two fixing posts 3124 protruding toward the door panel 311 on one side thereof, and the two fixing posts 3124 are spaced apart along the length direction of the door body 31. Of course, the present invention is not limited thereto.

[0036] Furthermore, the fixing plate 322 includes a first wall 3222 abutting against the door lining 312, a second wall 3223 located on a side of the first wall 3222 facing the door panel 311 and spaced apart from the first wall 3222, and a connecting wall 3224 connecting the first wall 3222 and the second wall 3223. The bending strength of the fixing plate 322 can be enhanced, thereby enhancing the stability of the connection of the slide rail bracket 33 and the stability of the drawer door 3 connected to the refrigeration compartment.

[0037] Specifically, the connecting wall 3224 connects the first wall 3222 and the second wall 3223 and is located at two ends in the length direction of the door body 31 .

[0038] In a specific embodiment, the fixing plate 322 is bent from the end of the connecting plate 321. Specifically, the fixing plate 322 is first bent from the end of the connecting plate 321 along the length direction of the door body 31, then bent toward the door panel 311, then bent in the opposite direction along the length direction of the door body 31, then bent toward the door lining 312, and then bent toward the connecting plate 321 along the length direction of the door body 31 to form the fixing plate 322. The fixing plate 322 and the connecting plate 321 are integrally bent and formed, which can enhance the strength of the reinforcing iron 32, thereby enhancing the stability of the connection of the slide rail bracket 33 and the stability of the drawer door 3 connected to the refrigerating compartment.

[0039] When fixing the reinforcing iron 32, firstly pass the connecting plate 321 of the reinforcing iron 32 from the door lining 312 toward the side of the door panel 311 through the through groove 3122, and at the same time, make the through hole 3221 penetrate the fixing column 3124 to pre-position the reinforcing iron 32; then, assemble the door lining 312 and the door panel 311 together and foam them, and fix the reinforcing iron 32 on the door lining 312 through the foaming material.

[0040] Furthermore, the drawer door 3 further comprises a slide rail bracket 33 connected to the connecting plate 321, wherein one of the slide rail bracket 33 and the connecting plate 321 is provided with a hook 331, and the other is provided with a bayonet 3211 matched with the hook 331. When the slide rail bracket 33 is fixed, it can be pre-positioned by the matching between the hook 331 and the bayonet 3211.

[0041] Furthermore, the slide rail bracket 33 is provided with a first screw hole 332, and the connecting plate 321 is provided with a second screw hole 3212 matched with the first screw hole 332; the drawer door 3 also includes a fastener 34 for simultaneously passing through the first screw hole 332 and the second screw hole 3212. After the slide rail bracket 33 is pre-positioned by the cooperation between the hook 331 and the bayonet 3211, the slide rail bracket 33 can be fixed by simultaneously threading the fastener 34 to the first screw hole 332 and the second screw hole 3212. It is easy to operate, and there will be no misaligned fixation. It can be accurately positioned during connection, so that the drawer door 3 installed on the refrigeration compartment can be prevented from being skewed.

[0042] In summary, the sliding door 3 in the present invention is configured such that the connecting plate 321 on the reinforcing iron 32 used for connecting with the slide rail bracket 33 passes through the through groove 3122 from the door lining 312 toward one side of the door panel 311, and the connecting plate 321 used for connecting with the slide rail bracket 33 is exposed to the outside of the door lining 312, so as to facilitate the connection of the slide rail bracket 33. At the same time, the connection can be precisely positioned, thereby preventing the sliding door 3 installed on the refrigeration compartment from being skewed.
